We offer Forced Air Ventilation System.Turbo ventilator is a combination of both natural and forced air ventilation system. It is a free spinning roof ventilator, which works on free wind energy. It functions as a natural ventilator when there is a difference in thermal or wind pressure between the inside and outside of the building which forces the air to move through the opening of the ventilator. It also act as a forced ventilation system when the turbo ventilator rotates to create a negative pressure within the building. Cooler air from outside rushes into the negative space within the building in order to maintain an equilibrium condition.
